Giant Box One Full Suspension Downhill Mountain Bike Information

INTRODUCTION

I was given one of these bikes many years ago for christmas (1997), it has served me well over the years and I was shocked to see that the internet is pretty empty for information on this fine machine. I am going to dedicate this page to compiling facts and specs from the original design. I have also collected some pictures in the gallery at the end of the page. The 1998 version was blue/yellow with Magura hydraulic rim brakes and RST front dampers. The 1999 version was red/black with diatech disc brakes and Suntour front forks.

COMMON FAULTS

Unfortunately there was a common design fault with the Giant Box One. It would generally last one or two years then the frame would crack. My personal Giant Box One had this problem and I have seen many more examples with the same issue. Once this happens it is a write off.
